The generalisation of screening campaigns for detection of breast cancer lead to the discovery of many infraclinical lesions, i.e. only detected by mammograms.
The surgeon will therefore need to specifically specifically locate the tumour: either using the 'hook' technique (the radiologist places a small specific catheter near the tumour) or after coloration of the tumour with a vital dye by the radiologist on the same morning as the surgical procedure.
The surgeon will then proceed to a very careful surgical approach of the tumour which should also respect the breast morphology.
The tumour exeresis should be complete.
To verify the completeness of the surgical resection, specific mammographic radiographies of the surgical specimen will be performed.
The aesthetic result of lumpectomy is generally good or very good, although the adjuvant radiotherapy, which is necessary to reduce the risk of local relapse, may give a sclerotic aspect to the mammary gland. However, psychologically, this breast retraction is better tolerated than radical mastectomy.
